I, too, am in need of an RGB cable. Even though I live in Brazil, I have monitors that accept 50 Hz, 15 kHz RGB. But they don't have a SCART connector, they have a VGA DE-15 female connector with R, G, B, HSync, VSync and ground in the usual places. Audio goes to a female stereo P2 plug in the monitor.
I could very easily build this cable out of Zozosoft's cable, but it'd be a waste to cut off the SCART connector. I'd be happy with either the E128 compatible edge connector only, ot it wired to a cable and nothing on the other side.
